Microsoft released another incremental update of Windows 10 on Wednesday, Build 9879, with new gestures, an improved OneDrive file management system, and the ability to turn off the new “task view” and search buttons.

If your Windows 10-equipped PC is plugged in and sleeping, chances are that it’s already downloaded the new build—assuming that you’ve opted in to the “Fast Ring” of updates. Microsoft said Build 9879 would be the last of 2014, although users can expect a new release early next year, Gabriel Aul, the engineering general manager within the Operating Systems Group at Microsoft, wrote.

Apparently, however, some wanted a purer Windows 10 experience. The new build adds a checkbox menu option where you can simply choose whether or not those features appear as icons in the toolbar. What appear to be the flagship features, however, are a simplified, logical OneDrive experience, and five new three-finger gestures to swipe through Windows 10’s user interface. A third, Snap Assist, now also works across multiple monitors.

Don’t like the Task View and Search buttons in the Windows 10 taskbar (at left)? Get rid of ‘em.

Why this matters: Microsoft continues to stride toward a release of Windows 10 sometime late in 2015, arm-in-arm with developers and enthusiasts who have provided feedback throughout the process. With Build 9879, the emphasis appears to be on adding flexibility where it’s needed, and simplifying things where it's not.

OneDrive: what are placeholders, anyway?

One of features that Microsoft added quietly as it scaled up the free storage associated with OneDrive was the way Windows handled files stored on your PC. In Windows 8.1, users have the option to store files locally or in the OneDrive cloud. But there’s a gray area: To save download time, OneDrive might decide to save a partial "placeholder" of the file on your PC. What wasn’t clear, however, was what were placeholders and what were full files—resulting in a bit of angst when users boarded a plane without Wi-Fi, Aul noted.

The new build adds some additional options to manage OneDrive within Windows 10.

That’s changed. Windows 10 will now use what Microsoft calls selective sync, where you’ll need to specify what’s saved to your PC, and what Microsoft keeps safe in its OneDrive cloud. Microsoft also appears to be killing the dedicated OneDrive app, allowing users access to OneDrive strictly through the File Explorer.

New gestures

Everyone loves quick-and-dirty methods to get things done, and Microsoft's Build 9879 adds a new set of three-finger shortcut gestures for trackpad users:

3 fingers up launches Task View

3 fingers down to Show Desktop

3 fingers flick to left or right to switch to previous app (go back 1)

3 fingers move left or right: Alt-Tab (Task View) pops up, and you can select the app you want (remove fingers to select)

3-finger tap: Search

Internet Explorer and MKV tweaks

Microsoft also said a small number of users—about 10 percent of those with the beta—would be upgraded to the new “Edge” rendering engine, designed for improved compatibility with the various sites on the Web.

Compatibility is also the name of the game with the MKV video file container, which was added in Build 9860. In Build 9879, users can now play MKV files directly from Windows Media Player, including desktop and modern apps), along with proper thumbnail images and MKV support.

An Improved Windows Insider app

Microsoft also said it might rely less on official blog posts in the future and focus more on direct communication with users via the Windows Insider app that users subscribe to when they join the beta. Users should have an easier time submitting feedback and seeing the feedback others have sent, Aul said.

A number of other, smaller tweaks include different folder icons, for example, and the use of a “hamburger” (layered bars) icon in certain apps to allow access to the Charms or settings.
